In [1]} a new approach was explored where apart from having non-universal WCs affecting only \(b \rightarrow s \mu ^+ \mu ^-\)  decay, one can also have universal WCs equally affecting all \(b \rightarrow s \ell \ell \)  processes, \(\ell =e,\,\mu ,\,\tau \) . Although LFUV new physics contributions are mandatory to explain
\(R_{K^{(*)}}\)  anomalies, a universal new physics contribution which is the same for all leptons
is not ruled out even though measurements in \(b \rightarrow s e e\)  sector are consistent with SM predictions. In fact, such a contribution gives rise to scenarios with a statistical significance at least as relevant
as that of only LFUV framework and can also motivate the construction of new models beyond SM including not only LFUV but also LFU new physics contributions [1]}, [3]}, [4]}.
